' CHARLES s. WHITWORTH, or CEDAR rALLs, IOWA.

- To all whom it mag/concern Be it known that I, CHARLES S. WH -r- WORTH, a citizen of the United States, res1ding; at Cedar F all's, in the county of Blackhawk and. State of Iowa,-have invented certain new and useful Improvements in Guide- Furrow-Forming' Attachments for Traction- Rigs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to traction gang rigs of that type wherein a gang of drills, seed ing machines, or other land cultivators are drawn from a traction engine, and the traction engine isguided by a forwardly projecting guide mechanism including a guide wheel arranged'to run in a furrow or lineal depression previously formed in the ground. When such a traction engine is employed in connection with gang plows, the last, or land side furrow may be used to direct the travel of the guide wheel, but when cultivators, such as drills or seeding machines or harrows are drawnin a gang from the traction engine, no definite or marked furrow is formed which is capable of use to direct the travel of the guide wheel. My invention provides a guide: furrow former for use in connection with traction rigs ofthe character above noted, and to such ends, generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims. v

Preferably, the improved guide furrow former isin the form of a rotary disk carried at the, end of a'long arm projecting laterally from a traction rig and ofiset therefrom, such a distance that on one course of travel of thetraction rig the guide furrow will be formed on the proper line of travel for the traction engine guide wheel on the next course or trip.

The invention is illustrated in the accompanying drawings wherein like characters indicate like parts throughout the several views. I i 1 Referring to the drawings, Figurel is a plan view illustrating the invention; Fig. 2 is a plan view of the guide furrow forming attachment removed from working position, some parts being broken away; Fig. 3 is a rear elevation of the parts shown in Fig. 2, some arts being broken-away and some parts icing sectioned; and Fig. 4 is al en GUIDE-FUBROW-FORMING ATTACHMENT FOR TRACTION-316:5.

Of the parts of the traction engine, the numeral 1 indicates the main frame, the numeral 2 the rear or traction wheels, the numeral 3 the pivoted front axle and the nu meral 4 the front wheels.

Of the parts of the forwardly projecting guide mechanism, the numeral 5 indicates a guide frame which, at its rear end, is attached to the front axle 3 of the traction engine for horizontal {swinging movements Specification of Letters Patent.

gine; and the numeral 11 indicates, as entireties, a gang or plurality of drills,seeders,

or similar cultivating machines attached to and drawn from the said gang frame 9.

The guide furrow forming attachment, as

preferably constructed, comprises a long telescopically extensible or adjustable arm made up of tubular sections 12 and 13, the

latter of which is telescoped into the former.

The inner end of the larger tube 12 is con veniently attached to one side of the gang 1 frame 9 by a hinge or pivot joint 14 which permits of horizontal angular adjustment to the said arm, and which has sufficient play to permit of a considerable of a vertical movement of the outer end of the said arm. The-extreme outer end of the smaller tube 13 is bent slightly downward at an angle, and thereon is journaled a furrow former preferably in the form of a concavo convex disk 15 set at the proper angle to form the desired guide furrow. The desired longitudinal adjustment of the tube 13, in re spect to the tube 12, is maintained by a set screw 16.

The arm 12'13 is held approximately at side of the main frame 1 of the traction engineand having branches 17 and 17' attached, respectively, to the tubes 12 and 13.

The disk 15 will be properly held to its work by its own weight and by the weight of the arm 12-13, but to limit the depth of the furrow which it will cut, and to support the same above the groundin an inopera end of the stem 18 is connected by a link 20 to a latch lever 21 that is pivoted to and cooperates with a latch segment 22, rigidly secured to the said tube 13.

VVlienthe guide furrow forming disk 15 is properly adjusted, it should, with the arrangement illustrated, be offset toward the left, a distance from the near side of the left hand drill 11, a distance which is approximately" equal to the distance that the guide wheel 6 is offset toward the left from the right hand side of the right hand drill 11. When so arranged, it will form a furrow on the line marked y on Fig. 1, which, from the pivotally formed guidefurrow y is offset approximately the distance equal to the width of the swath that is worked or covered by the gang of drills. Hence, the guide furrow 2 formed on one trip or course will be on the proper line to guide the guide wheel 6 on the next trip or course. With this. arrangement, therefore, the guiding of the rig may be accomplished automatically, by the guide wheel6 running in a previously formed guide furrow; his automatically guiding action not only lessens the labor in themanipulation of the traction rig but insures accurate and proper travel of the rig necessary to completely cover the ground withs'eed or to completely cultivate the same without leaving any black or untouched surface spots or space. I

The attachment is of small cost, efficient for: the purposes had in view, and may be easily applled and easily removed from a traction rig of the character noted.
